3 Claims. (Ol.--l31181) The present invention relates to smoking pipe structures and more especially to pipe structures providing an arrangement for producing a cool, dry and controlled smoke.

. An object of the present invention is to provide a filter for removing oils and tars from tobacco smoke and which can be readily and easily cleansed for reuse thereof.

A further object of the present invention is to provide a pipe structure which is economical to manufacture, yet permits the firing of tobacco therein to be controlled as desired, and provides a smoke which is relatively cool, dry and free from objectionable ingredients such as oils and tars.

Another important object of the present invention is to provide a pipe structure having an arrangement for controlling the firing of tobacco therein, yet which permits filters used therein to be removed and replaced simply and quickly.

And a further object of the present invention is to provide a pipe structure having means for removing moisture from the tobacco smoke, which I does not leave any dampness within the firing section of the structure and permits the entire tobacco therein to be consumed.

From the accompanying drawing and. the description thereon, further objects will be in part pointed out and in part obvious.

In the drawing:

Fig. 1 is a side view of the smoking pipe comprising the present invention, part of which is shown in elevation and the remainder being a cross section thereof showing the interior.

. Fig. 2 is an enlarged detail cross sectional view of the bowl portion of the pipe shown in Fig. l with the tobacco supporting members in their extended position with burning tobacco represented thereon and showing broken away portions of two of the telescopic sections showing the angle of the threads thereon.

Fig. 3 is an enlarged detail cross sectional view of the bowl portion of the present invention with the tobacco supporting means in their nestled position. I

Fig. 4 is a top cross sectional view taken in the direction of the arrows on line 4-4 of Fig. 2.

Fig. 5 is a top cross sectional view taken in the direction of the arrows on line 55 of Fig. 3, and

Fig. 6 is a side perspective view of a decagonal tube which forms a part of the present pipe structure.

- Referring now more particularly to the accompanying drawing wherein like reference characters designate like members, reference character I indicates a tubular member which forms a pipe bowlmember'z having a pipe stem 3 formed with and connected to the base portion thereof. The 5: interior of tubular member I has the configuration thereof formed similar to the exterior and the entire member is formed from a lightweight metal or may be molded from a plastic composition.

A mouthpiece 4 having a longitudinal opening 5 extending therethrough has stepped portion 6 thereof inserted within the open end of stem 3 and the exterior surface shaped to combine with stem 3 for forming a stem and mouthpiece of the usual appearance for such members. Slidably inserted within the open end of bowl portion 2 of the tubular member I is a stepped portion 9 of tubular ring 1, which ring is formed from a moisture-absorbing and heat-insulating material, as for example meerschaum, and which ring 1 has a centrally located bore I0. Said bore I0 is shaped havinga number of equal walls which form a regular decagon when viewed from the top or bottom thereof. The periphery of ring I is formed circular and is of a diameter equal to thed ameter of bowl portion 2, in order that said periphery of ring 1 extends contiguous from the periphery of bowl portion 2 to simulate therewith the usual bowl portion of a smoking pipe. Further, said ring 1 has a series of openings 8 formed extending from the bore I0 thereof through to its bottom face. The interior base of bowl portion 2 has a vertically extending decagonally shaped flange 33 formed therewith for receiving in a 35 close fit the lower end of a metallic tube 32 having a decagonal cross-sectional configuration, which tube 32 is of sufiicient length to extend from within flange 33 upward to contact with the bottom of ring I. The bore of tube 32 is similar to and in line with bore ll] of ring I. The ten walls 36 which give tube 32 its decagonal shape form with the interior of bowl portion'2 .a passageway 40, which passageway is closed at its upper end by ring 1 but is in connection with the bore I0 of ring 1 by means of openings 8. Formed through the tubular member I at a point centrally located within flange 33 is. an opening 39. Positioned within and extending from opening 39 is a flanged tubular section I5 having righthand threads l6 formed upon the periphery'thereof and lefthand threads 4| formed at the upper portion of its bore. The flange 34 of section l5 contacts the inner face of tubular member I and thereby prevents section 15 from moving outwardly therefrom. A second tubular section 11 having lefthand threads 2| formed upon a periphery thereof in threaded engagement with threads 4| of section I5 is sized and shaped to be entirely received within the bore of section I5. The lower peripheral portion of section I1 has a blank portion I9 formed therewith and' which blank portion I91 prevents the section I l'from being unscrewed fromvvithin section I5 more than is desirable. Similar to section I1 are sections 20, 22, 23 and 24, all of which have lefthand peripheral threads 2| and blank portions I9. threads 4I formed at the upper portion of their bore and peripheral threads 2| of sections. 26, 22, 23 and 24 are respectively in threaded engagement with interior threads 4| of sections I1, 20,.

Sections I1, 20, 22, 23 and 24 have 22 and 23. a length equal to the length of the bore of section I5 and by screwing one within the other, will nestle within section I5, as shown in Fig. 3. A plate 26 having an edge thereof shaped similar to and being substantially of a diameter equal to the bore of decagonal tube 32 is connected to tubular section 24 by a threaded rod 25, which is in threaded engagement with threads 4| formed within the bore of section 24.

tends completely across tube 32 in a horizontal position and is in sliding contact therewith.

Enclosing the tubular sections within section [5 is a knurled knob II formed having a peripheral vertical flange l3 and a tubular flange I2.

g of knob II is formed flat in order to permit the pipe structure to be supported thereby upon any flat, level surface whenever this is desirable.

Carried by plate 26 is a moisture-absorbing button 21 shaped from meerschaum or like materials, which is formed having the edge thereof tapered and comprising a series of walls 29. Said walls- 29 cause the upper face of button. 21 to form a decagon similar to the decagon formed by the bore I!) of ring 1 as well as the bore of tubular member 32. of button 21 is sufficient to cause the top edge thereof to slidably contact bore I and the bore of tubular member 32. Extending from the upper face of button 21 through to each wall 29 thereof is an opening 28.

Positioned within passageway 40, as bestshown in Figs. 4 and 5, is a filter 35. Said filter 35 is shown as a tubular screen having a circular periphery and a decagonally shaped bore in order that the same may completely fill passageway 40 between tubular member 32 and bowl portion- 2. The filter screen is formed from aluminum threads interwoven sufiiciently close to cause the smoke passing therethrough to thoroughly contact many surfaces presented by the aluminum threads and yet permit said smoke to readily pass therefrom through to stem 3. Within stem 3 is a secondfilter 311 also formed of aluminum thread interwoven in a manner similar to filter 35, having a cylindrical shape and com pletely filling the bore of tubular member 3.

Said sections further have interior This connection positions plate 26 in such a manner that it ex- The diameter of the upper face Said filter 31 is arrested from moving within the bore of stem 3 more than a given distance by means of a circular flange 38 formed with the bore of said stem 3.

The filters 35 and 31 may also comprise aluminum wool, spun aluminum or aluminum thread in a closely matted condition and given a tubular form for being readily inserted withinv passagewayAIJ or a cylindrical form for beingmounted within the bore of stem 3.

In assembling the members comprising the pipe structure, section I1 is screwed to within section I and likewise, sections 20, 22, 23 and 24 are respectively screwed into sections I1, 20, 22 and 23, all of which insertions are made from the bottom portion of the receiving section inwardly until all of the sections are nestled, as shown in Fig. 3. Plate 26, by means of projection 25, is connected to section 24 and the telescopic sections, together with this plate, are placed within the base of bowl portion 2' by inserting section I5 throughopening 39' thereof until this motion is arrested by flanges 34'. At this time, knob EI is screwed onto section I5 by a righthand rotation until the inner bottom face thereof contacts the bottom edge of section I5. Decagonal tube 32' is thenpositioned within bowl portion 2 and flanges 33, which flanges 33 prevent the rotation of said tube 32 and thereby, plate 26, which is in longitudinal slidingcontact with the bore of said. tube 32. Filter 35 is then slidinto position between tube 32 and the interior of bowl portion 2 to completely fill passageway 40. Meerschaum button 21 can then be slid longitudinally of tube 32 until it is positioned upon plate 26 and the stepped portion 9 of tubular ring 1 is then positioned within bowl portion 2 contacting the top edge of tube 32' for retaining the same in position and at the same time, closing passageway 40' at the upper portion thereof.

Filter 31 is inserted within the open end of stem portion 3' until arrested by flange 38, at which time the stepped portion 6 of mouthpiece 4' is inserted within the open end of stem 3 and is supported thereby.

A smoker using this pipe construction can place within tube 32 and bore I6 tobacco 30 until the same is supported by the button 21 and fills the space thereabove up to and a little above the openings 8 of ring 1. Upon igniting the tobacco and the smoker drawing through mouthpiece 4, clinkers 3I will result. By rotating knob I I, telescopic sections I1, 20, 22, 23 and 24 will be caused to rotate and ascend, due to their threaded inter-engagement and the smoker, by moving the tobacco 3 upwardly in this manner, can adjust the position of th clinkers 3! relative to the top of the ring 1, thereby controlling the amount of oxygen fed to the burning tobacco until the smoker determines at which :height within or above the ring 1 the clinkers 3I should be positioned to suit his particular taste. As the tobacco is consumed, the knob II is rotated in order that the plate 26, button 21* and tobacco 30 will be progressively advanced upwardly so that the clinkers 3I may at all times be kept at the predetermined position. Due to the slidable contact of plate 26 with tube 32, the same is not permitted to rotate and therefore, sections I5, I1, 20, 22 and 23 will rotate upon the rotation of knob II, but due to the non-rotatable condition of section 24, due to its connection to plate 26,'these aforementioned sections will gradually unscrew one from the other until blank portions I9 contact threads 4 I, at which time the unscrewner, tobacco 30 may be consumed completely down to the top face of button 21.

Button 21 and ring I are also of a heat-insulating nature and thereby prevent the heat from clinkers 3| from being conducted to either tubu- ,lar member |,plate 26 or tube 32 and asthe smoke comes from opening 8 to Within passageway 40, it will contact these cool and heat-conductive members, whereupon, it will also be cooled.

Filter 35 being formed of fine aluminum threads, aluminum wool or spun aluminum, by closing passageway 40, causes all of the smoke from openings 8 to be drawn therethrough. The smoke will contact this mass of fine aluminum and the moisture depositing heavy oils and tars therein will, of its own accord, adhere to the aluminum and the purified smoke will pass therefrom. The smoke from passageway 4|] will then be drawn to within the aluminum filter 31 within stem 3 and any tars or oils which may have escaped through filter 35 will adhere to the aluminum of filter 31. Both filters 35 and 31, being of a lightweight metallic nature, are therefore also of a highly heat-conductive nature and being in direct contact with tubular member I, they will readily conduct the heat from and thereby cool the smoke passing therethrough.

After the pipe has been used for a time, filters 35 and 31 will become contaminated with the oils and tars they have removed from the smoke passing therethrough. Therefore, by removing ring 1 and mouthpiece 4, both of these filters may be readily removed, that is, filter 35 from passageway 40 and. filter 3! from the bore of stem 3. These filters may be positioned .within a container having therein a known liquid solvent such as, for example, carbon-disulphide, ether or carbon-tetrachloride and the heavy oils and tars thereon will be readily dissolved thereby without in any manner affecting the aluminum of the filter. After a period sufiicient for the complete dissolving and removal of the oils and tars, filter 35 may be replaced within passageway 40 and ring I slid back into position and, likewise, filter 31 repositioned within the bore of stem 3 and mouthpiece 4 replaced. Then the pipe can be further used and the filters will function as when new.

When the pipe is not in operation, knob l I may be given a lefthand rotation and the telescopic sections will return to their nestled position. Due to the protection of'button 21, tube 32 and plate 26 will at all times remain free from moisture and tacky substance and due to the firing of the tobacco within the ring 1, these members 26 and 32 do not at any time need to be removed for cleaning and there will be no contaminations upon the interior wall of tube 32 preventing the efficient longitudinal movement of plate 26 and button 21.
